Problems solved by technology

Although the cast-in-place concrete floor slab solves the problems of earthquake resistance and cracking, a large number of formwork is used during construction, which not only increases the cost, but also slows down the construction speed and prolongs the construction period.

Embodiment Construction

[0073] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0074] As shown in the accompanying drawings, the present invention includes a prefabricated thin plate 1, a formwork 2, a hidden rib 3, and an upper plate 4. A formwork 2 is fixed on the prefabricated thin plate 1, and a dark space is arranged between adjacent prefabricated thin plates 1 or formworks 2. The rib 3 and the upper plate 4 cover the formwork 2 and are connected with the hidden rib 3 as a whole. It is characterized in that the formwork 2 is provided with at least one mold cavity that penetrates the surface of the formwork 2 with a transverse hole 5, The cast-in-place concrete enters the transverse hole 5 and together with the mold cavity of the transverse hole 5 forms a composite cast-in-place concrete reinforcing rod 6 . figure 1 It is a structural schematic diagram of Embodiment 1 of the present invention. In the attached drawings, 1 is t...

Abstract

A kind of combined hollow building plank with reinforcing steel bar in it, comprises the prefabricate lamella, the mould hull, the hidden rib, the upper plank, the mould hull fixed on the prefabricate lamella, setting the hidden rib between prefabricate lamella and the mould hull, and close together to them, overlaying the upper plank on the mould hull, and connect with the hidden rib for the integral whole, its characteristic lies in of setting on mould hull at least one mould cavity pierce through the mould hull of the horizontal hole of the mould hull surface, Sprinkled the things into the horizontal hole to form the compound and strengthened pole with the horizontal hole. Thus, the subjected piece and the force conductive piece of building plank form in the mould hull, improves the mechanics function of the building plank consumedly.

Description

(1) Technical field [0001] The invention relates to a composite reinforced concrete hollow floor slab. (2) Background technology [0002] At present, most of the buildings with brick-concrete structure and frame structure use prefabricated hollow-core slabs as floor slabs. This kind of floor slab has the advantages of fast construction speed and low cost, but because there is no firm connection between two adjacent prefabricated hollow-core slabs , Only cement mortar is used to fill the gaps, so not only the integrity is poor, which is not conducive to earthquake resistance, but also cracks and water seepage often occur, causing great inconvenience and psychological pressure to the residents. In order to solve the above problems, many buildings have adopted the method of cast-in-place concrete floor slabs (hollow, solid). Although the cast-in-place concrete floor slab solves the problems of earthquake resistance and cracking, a large number of templates are used during cons...
